LOAF-FORMING MACHINE.

Specification of Letters Patent.

Patented Mar. 24, 1914.

Application filed June 29, 1912. Serial No. 706,639.

To all whom it may concern Be it known that I, HERBERT HACKSTEDDE, a citizen of the United States, residing at Cincinnati, Ohio, have invented a new and useful Improvement in Loaf-Forming Machines, of which the following is a specification.

My invention relates to loaf forming machines of the class adapted to the use of bakers or others for forming loaves of dough or other suitable plastic material, and the o jects of my improvement are to provide means for adjusting the pressure plate in relation to the drum in such manner as to maintain one end thereof at a uniform distance from the face of the feeding roller, and to provide simple and durable construc tion and assemblage of the various members for securing facility of operation and efficiency of action.

These objects may be attained in the following described manner as illustrated in the accompanying drawings, in which Figure 1 is a longitudinal vertical section of a loaf forming machine embodying my improvements, and Fig.2is a side elevation.

In the drawings, 1 represents the legs, 2 the frame thereon, and 3 a bracket secured on the frame and provided with the hopper 4. The feed roller 5 and the pressure roller 6 provided with the usual end flanges 7 and the pressure roller 8 all of the usual length are journaled in the side walls of the bracket 3. Blocks 9 slidably mounted within the grooves 11 formed in the side walls of bracket 3 are adjustable therein in the axial plane of roller 6 by means of the adjusting screws 12. A yoke 13 secured on the respective blocks 9 by means of cap screws 14 may be thereby pivotally adjusted in different vertical angles. Pressure rollers 15 and 16 j ournaled across opposite ends of said yoke are adapted to cooperate respectively with the rollers 5 and 6 and with the pressure roller 8 for forming the dough into a sheet in the ordinary manner. The adjustment of the blocks and of yoke 13 thereon provides the necessary adjustments for the rollers 15 and 16 in relation to the adjacent other said rollers. All of said rollers may be driven at the same peripheral speed and in the directions respectively indicated by the arrows by means of gears or sprocket chain connections (not shown) in the ordinary manner. The

usual scrapers 17, 18, 19 and 21 are provided for the respective rollers 5, 8, 15 and 16 as shown in Fig. 1, and the faces of rollers 5 and 6 are very close together but without being in contact. a

The drum'22 provided with end flanges 23 which overlap the ends of the feed roller 5 1s journaled in bearings 24 which are secured on the frame, and it may be driven in the usual manner (by means not shown) in the direction of the arrow and at somewhat greater peripheral speed than that of the feed roller 5. The face of the drum may be roughened or preferably covered with canvas 25. Similar brackets 26 secured on the frame near the ends of the drum are formed with a series of slots 28 which are extended beyond the flanges 23. The said slot adjacent to the feed roller is on a radial line of the drum and the other slots are successively mclmed at increasing angles to the radii of the drum and in a direction opposed to that of its rotation. The usual curved pressure plate 31 is formed on its edges with a series of projecting ears 32 whereby it may be supported on rods 33 which are slidably supported at their end portions within the cor responding opposite slots 28. Similar members 34 are mounted contiguous to the corresponding brackets 26 and are formed with slots 35 adjacent to the corresponding slots 28 and in slidable engagement with the ends of rods 33. Said slots 35 are successively inclined from the radii of the drum at increasing angles and in the opposite direction from the inclination of slots 28 as shown in Fig. 2.

A transverse shaft 36 supported by the legs and provided with arms 37 on its respective ends may be rotatively adjusted by means of the hand screw 38. Links 39 connect the said arms with crank pins 41 on the respective members 34 for moving and maintaining said members in different positions of rotative adjustment concentric with the drum. Owing to the shearing angles of corresponding slots 28 and 35 the rotative adjustment of the members 34 serve to slide the rods within the slots and thereby change the distance of the pressure plate in relation to the face of the drum and still maintain it in a concentric position thereto. In adjusting the pressure plate in this manner its end adjacent to the feed roller is moved approximately parallel to the face thereof for maintaining constant the width of the gap 4-2 between them for the passage of the sheet as of dough to the face of the drum.

A flour sifter 44; provided with a perforated bottom and with an ordinary vibrating or rotative brush 45 and mounted on the frame serves to discharge a small quantity of flour continuously within the inclined receptacle 4L6. Said receptacle is supported on the frame beneath the drum, and provided with a rotary brush 4:? driven in the ordinary manner and which serves to project the flour against the face of the drum to prevent the dough from sticking thereto. The receiving table 48thinged on the sifter 44 serves also as a removable cover therefor.

In operation the sheet of dough may be discharged by the feed roller into perpendicular contact with the face of the drum whereby said sheet may be coiled in an upward direction as it continues to contact therewith. The gravity of the sheet prevents any portion of it from being lifted by the drum before contacting therewith. When the coil is in this manner increased to a suflicient diameter, it automatically engages with the adj acent'end of the pressure plate and is carried along thereunder by the drum whereby the coiling of the sheet may be completed and the desired form given to the loaf before being discharged upon the receiving table. The adjustment of the pressure plate in relation to the drum adapts it to engage with unfinished coils of difierent diameters.

Having fully described my improvements, what I claim as my invention and desire to secure by Letters Patent of the United States is:

The combination of a rotative drum, fixed brackets adjacent to its respective ends and formed with a series of slots extending beyond the periphery of the drum, members adjacent to the respective brackets formed with similar cooperating slots, the slots in the brackets being successively inclined at increasing angles to the radii of the drum, and the cooperating slots in said members being correspondingly inclined in the opposite direction to form shearing angles therewith, transverse rods slidably engaging with corresponding slots in the brackets and members, a pressure plate secured on the rods concentric to the drum, and connections for rotatively adjusting said members for sliding the rods in the slots whereby the pressure plate may be adjusted in distance relations to the drum and with one of its ends in the same radial plane.
